Definitions

  • the invention relates to an internal combustion engine and, more particularly, to an exhaust system having a first and a second exhaust gas turbocharger for an internal combustion engine with eight cylinders in a V-design, a first cylinder bank being formed by a first, a second, a third and a fourth cylinder arranged in series side-by-side, and a second cylinder bank situated opposite the first cylinder bank being formed by a fifth, a sixth, a seventh and an eighth cylinder arranged in series side-by-side.
  • German published patent application DE 10 2004 057 129 A1 describes a V-engine having 8 cylinders (a V8 engine) with an ignition sequence (or firing order) of a 90° crank angle from one cylinder to the next.
  • Each cylinder bank of the internal combustion engine has four cylinders.
  • Two cylinders respectively of a cylinder bank lead into an exhaust line which, in each case, conducts the exhaust gases of the four assigned cylinders into an exhaust gas turbocharger.
  • the internal combustion engine therefore has two four-flow exhaust lines. Together, the two exhaust lines form an exhaust system. Before entering into the turbochargers, the exhaust lines can be connected with one another in an exhaust-gas-carrying manner.
  • One emission control system respectively is arranged in the exhaust system behind each exhaust gas turbocharger in the flow direction of the exhaust gas.
  • a disadvantage of the described embodiment is a so-called side-to-side action of the exhaust gases of the four cylinders each leading into an exhaust line, whereby a maximal opening duration of the charge cycle intake valves cannot be implemented.
  • an exhaust system having a first and a second exhaust gas turbocharger for an internal combustion engine with eight cylinders in a V-design, a first cylinder bank being formed by a first, a second, a third and a fourth cylinder arranged in series side-by-side, and a second cylinder bank situated opposite the first cylinder bank being formed by a fifth, a sixth, a seventh and an eighth cylinder arranged in series side-by-side.
  • the internal combustion engine has an ignition sequence of a 90° crank angle from one cylinder to the next.
  • the exhaust system has a first, a second, a third and a fourth exhaust line from the cylinders to the two exhaust gas turbochargers.
  • Two cylinders are respectively assigned to an exhaust line, and one exhaust turbocharger is respectively assigned to two exhaust lines.
  • the two cylinders assigned to the exhaust line have an ignition interval of a 360° crank angle, and the first and the second exhaust line assigned to the exhaust gas turbocharger have an ignition sequence offset from one another by a 180° crank angle.
  • the ignition interval amounts to a 360° crank angle of the two cylinders assigned to an exhaust line or a flow.
  • the turbine wheel of the exhaust gas turbocharger is therefore acted upon by exhaust gases at a 180° ignition interval.
  • the exhaust system embodiment according to the invention Due to the exhaust system embodiment according to the invention, a better charge exchange is achieved since a symmetrical identical filling with fresh air exists for all eight cylinders. As a result of the symmetrical identical filling, less residual gas remains in the individual cylinders, whereby the knock tendency of the internal combustion engine is significantly improved (knocking is reduced) In addition, fuel consumption is improved, particularly at full load of the internal combustion engine. Furthermore, very high torque values will already exist when the rotational speeds are very low. As a result, the so-called “turbo hole”—a weakening of the torque—in the lower rotational speed range—is almost completely eliminated.
  • the exhaust system according to the invention can be used for internal combustion engines operating according to the spark ignition principle, as well as for internal combustion engines operating according to the Diesel principle.
  • the exhaust system and the two exhaust gas turbochargers are mainly arranged in the V between the cylinder banks.
  • extremely short paths for the exhaust gas are achieved in the exhaust system. This minimizes flow losses of the exhaust gas and benefits the emissions as well as the fuel consumption.
  • the first and second turbochargers are twin-scroll turbochargers. This further development is particularly preferred for a two-flow exhaust gas turbocharger, in which case each flow is acted upon by exhaust gas from an exhaust line.
  • the first exhaust gas turbocharger includes a first turbine wheel and the second exhaust gas turbocharger includes a second turbine wheel.
  • the first turbocharger has a third turbine wheel and the second turbocharger has a fourth turbine wheel. Accordingly, each exhaust gas turbocharger has two exhaust gas turbines which each has a separate flow, one exhaust line respectively leading into each flow.
  • FIG. 1 is a schematic view of an exhaust system according to an embodiment of the invention for an 8-cylinder internal combustion engine having a V-design.
  • the internal combustion engine has a first cylinder bank 9 and a second cylinder bank 10 situated opposite the first cylinder bank 9 .
  • the first cylinder bank 9 has four cylinders 1 , 2 , 3 , 4 arranged in series
  • the second cylinder bank 10 also has four cylinders 5 , 6 , 7 , 8 arranged in series. Cylinders 1 and 5 , cylinders 2 and 6 , cylinders 3 and 7 , and cylinders 4 and 8 are arranged opposite one another.
  • An ignition interval from one cylinder to the next nominally amounts to 90°. In practice, however, the ignition interval (firing sequence) may vary from 85° to 95° as a function of the operating condition of the internal combustion engine.
  • two exhaust gas turbochargers can be arranged (not shown in detail).
  • the two exhaust gas turbochargers by way of an exhaust system 11 having the cylinders 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , can be connected with one another in a gas carrying manner.
  • the exhaust system 11 is constructed of a first exhaust line 11 a , a second exhaust line 11 b , a third exhaust line 11 c , as well as a fourth exhaust line 11 d .
  • the first exhaust line 11 a connects the cylinders 1 and 6 with one another in a exhaust-gas-carrying manner and leads into a first exhaust gas intake (first flow) of a first exhaust gas turbocharger (not shown in detail).
  • the fourth exhaust line 11 d connects the cylinders 4 and 7 with one another in an exhaust-gas-carrying manner and leads into a second exhaust gas intake (second flow) of the first exhaust gas turbocharger.
  • the second exhaust line 11 b connects the cylinders 2 and 5 with one another in an exhaust-gas-carrying manner and leads into a first exhaust gas intake (third flow) of a second exhaust gas turbocharger (also not shown in detail)
  • the third exhaust line 11 c connects the cylinders 3 and 8 with one another in an exhaust-gas-carrying manner and leads into a second exhaust gas intake (fourth flow) of the second exhaust gas turbocharger.
  • each of the first and the second exhaust gas turbochargers is a twin-scroll exhaust gas turbocharger.
  • an exhaust gas turbocharger with two exhaust gas turbines, each having a separate flow, can be used.
  • the exhaust gas turbochargers are arranged in the V between the cylinder banks 9 and 10 ; however, in another embodiment, the exhaust gas turbochargers may also be arranged on the outside, i.e., in front of, behind, and/or laterally on the internal combustion engine.
  • the exhaust system is preferably manufactured as a sheet metal component, again preferably in an air-gap-insulated construction.
  • the exhaust system could also be manufactured as a cast component which, however, would have disadvantages with respect to weight.
  • a composite construction as a combined sheet metal/cast component could also be used, as well as a liquid-cooled light-metal exhaust system construction. In the latter case, the cooling preferably takes place by way of a coolant of the internal combustion engine, in which case an aluminum alloy is preferably used as the light metal.
  • the exhaust system may be used for any 8-cylinder internal combustion engine operating as a 4-stroke engine, irrespective of whether it operates according to the spark ignition or the Diesel combustion principle.
  • each turbine of the exhaust gas turbochargers “sees” an ignition interval of a 180° crank angle. Depending on the operating condition of the internal combustion engine, this ignition interval may vary by ⁇ 5°. This is the maximally achievable ignition interval for an internal combustion engine with 8 cylinders. This maximal ignition interval leads to an optimal charge exchange because an exactly symmetrical identical filling is achieved for all cylinders 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 . Furthermore, less residual gas will remain in the cylinders 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , which leads to a lower knock tendency of the internal combustion engine.
  • the prolonged opening duration of the charge cycle intake valves or of the camshaft should be particularly stressed, whereby clearly higher power as well as higher torque of the internal combustion engine are achieved.
  • the fuel consumption in the full-load range is also improved.
  • Another important advantage is achieved at low rotational speeds because very high torques of the internal combustion engine are already obtained at very low rotational speeds.
  • a “turbo hole” a weakness of the torque in the lower rotational speed range—can be minimized so that this weakness will no longer occur during the driving operation in practice.
  • an extremely uniform action of the exhaust gas can be achieved upon the turbines, whereby their service life can be extended.
